So I just moved into a new house recently, and I'm setting up my WiFi. I have a gigabit modem connected to the main Deco. Standing in the same room as that deco, I get ~467mbps on my comcast 400mbps plan. So I went to setup the other deco's via ethernet (my house is wired with ethernet, I'm using a switch that's plugged into the deco), and I plugged them in, updated, and reset with the ethernet cables plugged in. I only get anywhere from 90-150mbps when I'm standing by either deco that isn't the main one, so I am assuming it's not using ethernet as the backhaul. So I went ahead and plugged my apple tv into the ethernet (the one that's connected to the switch), and got 349mbps on speedest. Much better. So I'm wondering, how do I set two of my deco's to use AP mode while having the one being the "main" unit and acting as a router?
HELP! Cannot figure out how to use ethernet backhaul on TP-Link Deco m5
